Re: Iterative visiting of all source files

I would prefer to use GTAGS as the main source of the lookup for CEDET. At
work we have a huge project. From what I have researched so far the
following are the stages required to set up using gtags (this is basically
my .emacs - at the beginning):

========portion of .emacs========

;; MODE: CEDET
(load-file "~/.emacs.d/bzr_cedet/cedet-devel-load.el") ;; This is the latest
dev' version ~~ 26th Jan 2015
;; Add further minor-modes to be enabled by semantic-mode.
;; See doc-string of `semantic-default-submodes' for other things
;; you can use here.
(add-to-list 'semantic-default-submodes 'global-semantic-idle-summary-mode t)
(add-to-list 'semantic-default-submodes
'global-semantic-idle-completions-mode t)
(add-to-list 'semantic-default-submodes 'global-cedet-m3-minor-mode t)
(semantic-mode 1)
;(global-ede-mode 1)
(global-semantic-decoration-mode)
;(semantic-show-unmatched-syntax-mode t)
;(speedbar 1)

;; MODE: GTAGS (backend for SEMANTIC)
(setq cedet-global-command
"c:/Users/me/Downloads/gnu_global_622wb/gnu_global_622wb/bin/global")
(semanticdb-enable-gnu-global-databases 'c++-mode t)
(semanticdb-enable-gnu-global-databases 'c-mode t)
(setq-default semantic-symref-tool
"c:/Users/me/Downloads/gnu_global_622wb/gnu_global_622wb/bin/global")

========END portion of .emacs====

Then,
(http://stackoverflow.com/questions/12791246/how-can-i-tell-if-cedet-is-using-gnu-global)
Eric tells us how to ensure we are using gtags which is basically:

1. M-x cedet-gnu-global-show-root RET
;;;;; For me, this correctly returns the root directory and this is, indeed,
where all the G* files are (such as GTAGS)

2. M-: (semantic-symref-detect-symref-tool)
;;;;; This brings back the string used in my .emacs file. Basically the
function returns:
"c:/Users/me/Downloads/gnu_global_622wb/gnu_global_622wb/bin/global"

Eric, you say in that stack overflow source: "it will give you a symbol
representing the tool it has chosen to use" - but I do not know what this means.

I still see no way to definitively finding out whether or not semantic is
using GTAGS.

Cheers.
